基于条件熵的多链路到达序列编码隐写分析
Steganalysis to multipath encoding based on conditional entropy
摘要
Abstract
Network steganography is a technology of covert communication which uses network data to transmit hidden message. In recent year, the focus of network steganography research is transforming from feasibility to improve conceal-ment. The steganography based on multipath encoding is proposed by this background, At present, there is no effective method detecting this new steganography. The steganalysis method of multipath encoding is analyzed firstly, and then the steganalysis method based on conditional entropy is proposed through the analysis of normal multipath data. The experi-mental results show that this proposed method can detect this steganography with satisfied result when the detection win-dows size equal 1200.关键词
